I'm looking for a photo of or dimensions for the wood support blocks inside a K200A head cabinet, that pleat mentions in this old post from December 2012:

"Which K200 head case are you looking for? There is a difference between the K200A series and K200B series cases. A series are about a half inch shallower in the depth of the A models. Bolt patterns are different and there are wood block spacers on the A models to help support the tranny and power transistors."
pleat

Also, what type of bolts were used to attach the K200A chassis into the head cabinet? Flat head, round head, hex head?

Thanks!

Mike

the plywood supports are 1/4" thick and as far as the size, you can measure the length or spread of the 4 power transistors and I'd figure an 1" wide. I'd measure the footprint in the power transformer area, I guess 4x4" square. The spacer blocks don't actually touch the bottom of the chassis or the power transistors, I think they are placed there in the event of a hard drop that might deform the bottom of the chassis. Round head bolts with a flat washer would work. Slotted or Phillips head isn't a big concern, just get what you can find locally.

Pleat as usual is right the wooden pad under the transformer is 4" X 4". On my K200A-4 head that is the only one in there. It is 3/8" thick plywood.

The five brass standoffs are threaded 10-32 and are 1/2" tall, so there is a 1/8" gap between the bottom of the chassis and the top of the square pad. The screws for my head are pan head phillips with 1/2" diameter flat washers. They are 1 1/2" long.

As it happens, my K200A-4 head is apart right now, so if you need some information let me know. With the holidays coming up I may not be able to get to it right away, but I will try.

Not sure how far along you are on your remake but there has been several empty K-200 cabinets for sale on Ebay over the past couple of months.......most resent was one in blue for $65....and the usually black of course more frequently. Recovering the head is going to set you back some money too......$200 plus mark.

You will want to know if the K200 head cases are for the A or the B series. The A series will slide into a B series and you will have to re-drill for the mounting bolts. Sliding a B series chassis into a A series head case, the back of the amp will stick out since is is deeper in depth than the A series. I agree, if you can buy one on ebay for 65.00 and with your K200A series amp chassis, you can make it work if they are a B series case. Just add the supports inside if you like and rock on.

Thanks for all the information and suggestions, guys!

The cabinet is completed and while it ain't fine woodworking, it is comparable to the plywood boxes from the Chanute factory.

It is the correct depth for the K200A series chassis and the power transformer support block is included.

I used oak veneer plywood as I had some on hand and I brushed two coats of shellac to seal the outside surfaces.

Now, I need to find an upholstery guy, who can recreate the Kustom T&R in red sparkle Zodiac!

I've got a guy here in Marshalltown Iowa that made the T&R for one of the members here and then the member was going to install it himself. My guy here quoted me a price of $200 including the material for one of my heads. If interested private message me and I can give you a phone number and you can talk to him direct. He has access to all the Zodiac material as well as some new stuff that looks pretty sharp in all kinds of colors.
